Hi All, Alex Alex, you mentioned you might know why Kamailio is timing out do unanswered INFO request from Asterisk. I am still unable to resolve this, but I have verified all the INVITES to the ACK's and they seem ok. I do get connected for about 30 seconds though, the call just drops after that and it does appear to be caused by the none response to INFO requests.

I am including a snippet of the last part of the Wireshark dump that occurs right before the dropped call. There are many of the very same INFO Request going from Asterisk to Kamailio; there is also another INFO request in the middle that was different (but only occurs a few times). The INFO Requests do have ;tag in the To header. I noticed that Asterisk replies '200 OK' to INFO request from Kamailio but Kamailio does not send '200 OK' for INFO requests from Asterisk. I did try forcing Kamailio to send a '200 OK' when it gets an INFO request, but that did not work. You will see that there are a bunch of INFO request to Kamailio from Asterisk, then Kamailio sends a 408 Request Timeout , then Asterisk send a BYE and call drops shortly after.

"I think" > this is why some calls are dropping. Does this make any since? It does. Is the INFO message in-dialog[1] or out-of-dialog? [1] Does it have a ;tag attribute in the To header? -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/ _______________________________________________ Kamailio (SER) - Users Mailing List sr-users@lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users _______________________________________________ Kamailio (SER) - Users Mailing List sr-users@lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
